the "Precautionary Prayers" consisting of ١ unit. and should perform sajdatus sahu for the additional salaam.
١٢٣٤. If a person realizes during the
"Precautionary Prayers" that the deficiency in his prayers has been more
or less than his "Precautionary Prayers" and it hecannot complete his
"Precautionary Prayers" according to the deficiency in his original
prayers, he should abandon the "Precautionary Prayers". In this event he
should, ifpossible, make up the deficiency of the original prayers, and
it this is not possible he should offer the prayers again. For example,
if the doubt is about ٣ and ٤ units, andwhile he is offering ٢ units of
"Precautionary Prayers" in the sitting posture he recollects that he
offered ٢ units of the original prayers, and as he cannot treat ٢
unitsof prayers offered in the sitting posture as equivalent to ٢ units
offered in standing posture, he should abandon the "Precautionary
Prayers" being; offered in the sittingposture. Hence, if he recollects
before the first bowing of the "Precautionary Prayers (that he offered ٢
units of the original prayers) he should make up the deficiency inthe
original prayers and if he recollects it after that, he should offer the
prayers again.
١٢٣٥. If a person doubts whether or not he
offered the "Precautionary Prayers" which was obligatory on him and if
the time of prayers has passed he should ignorehis doubt. And if he has
time at his disposal, and much time has not passed between the doubt and
the prayers, and he has also not performed an act like turning away his
facefrom Qibla which invalidates the prayers, he should offer the
"Precautionary Prayers". And if he has performed an act which
invalidates the prayers or a good deal of time haspassed between the
prayers and the doubt he should ignore his doubt.
١٢٣٦. If a person increases a rukn (basic
element) in the "Precautionary Prayers" or, for example, offers ٢ units
instead of one, his "Precautionary Prayers" becomesvoid and he should
offer the original prayers.
